TekTone SF155B Emergency Pullcord Nurse Call Station

The TekTone SF155B is a UL 1069 Listed emergency nurse call station with a 6-foot pull cord, 1.1-inch red pull-down lever, and flashing call-placed LED indicator for Tek-CARE NC110, NC150, and NC200 nurse call systems. Designed for patient rooms, bathrooms, and other dry indoor locations requiring emergency assistance signaling, it supports pull-cord or lever activation and call cancellation at the point of origin. The station features a flame-retardant UL 94V-0 plastic faceplate, plug-in electrical connectors, and single-gang mounting for integration with compatible nurse call equipment.

TekTone SF155B Emergency Nurse Call Pull-Cord Station with LED Indicator

The TekTone SF155B is a wall-mounted emergency nurse call station designed to allow patients, residents, and building occupants to request immediate assistance through compatible Tek-CARE nurse call systems. Manufactured by TekTone Sound & Signal, the SF155B provides two methods of emergency call activation: a supplied 6-foot pull cord and a large, 1.1-inch-wide red pull-down lever clearly marked for emergency use. Pulling the cord or moving the lever downward initiates an emergency call through the connected nurse call system, providing a convenient means of requesting assistance from different positions within a room. A built-in flashing red call-placed LED visually confirms that the emergency signal has been activated. The station is designed for patient rooms, assisted living facilities, skilled nursing centers, hospitals, and other healthcare environments requiring dependable emergency call initiation. Its simple mechanical controls and compact white housing provide a recognizable emergency assistance interface without requiring a touchscreen or separate handheld call device.

The SF155B incorporates a pull-down call/cancel switch, sealed LED indicator, and circuit-board-mounted electronic components to support reliable emergency signaling through compatible TekTone equipment. The station's 6-foot nylon pull cord extends the activation point below the wall-mounted unit, allowing users to initiate a call without reaching the main control lever. Alternatively, the station can operate without the cord as a pull-down emergency switch when the installation does not require remote cord activation. When a call is placed, the red LED flashes to confirm that an emergency request has been registered, while associated master stations and corridor lights provide notification according to the connected nurse call system's configuration. The SF155B supports call cancellation at the point of origin, requiring an attendant or authorized user to return the call/cancel lever to its normal position after addressing the request. This local reset arrangement helps ensure that emergency calls are not inadvertently cleared solely from a remote annunciation location. The device also supports compatible corridor zone light signaling, allowing emergency calls to be identified through associated hallway notification equipment.

The TekTone SF155B features a flame-retardant UL 94V-0 plastic faceplate with internal switching and electronic components mounted on a printed circuit board. Its call-assurance LED is sealed in plastic to protect the indicator assembly, while plug-in electrical connectors simplify connection to the compatible nurse call wiring system. The station measures 4.8 inches high, 3.2 inches wide, and 1.2 inches deep (122 x 81 x 30 mm), providing a compact wall-mounted profile suitable for installation near patient beds, room entrances, and approved emergency call locations. The SF155B mounts to a single-gang electrical ring or a single-gang ring installed with a double-gang electrical box, allowing integration with standard electrical mounting hardware. The device is intended for ordinary indoor environments and must be positioned away from locations where direct water contact could occur. Manufacturer instructions specifically caution against installing the SF155B where it may be exposed to water, making a separately approved water-resistant emergency station necessary for showers, wet bathrooms, or other moisture-prone locations. Proper pull-cord placement and mounting height must follow the facility's accessibility requirements and applicable healthcare installation standards.

The TekTone SF155B is designed for Tek-CARE NC110, NC150, and NC200 nurse call systems, providing an emergency signaling point that communicates with compatible master stations, corridor lights, and supporting nurse call equipment. The manufacturer identifies the SF155B as UL 1069 Listed for hospital signaling and nurse call equipment under UL File E71599, supporting its use in qualifying healthcare communication installations. Its straightforward operation makes it suitable for assisted living communities, nursing homes, rehabilitation facilities, patient care areas, and other institutional environments that depend on centralized emergency assistance notification. The SF155B differs from conventional patient stations that require a detachable call cord plugged into a receptacle because it incorporates a permanently attached emergency pull cord and a dedicated mechanical call/cancel lever. It also differs from the newer TekTone SF133 emergency station, which is designed for additional Tek-CARE platforms and supports a separate gasket accessory for moisture-prone installations. The SF155B requires a compatible TekTone nurse call system and does not function as a standalone audible emergency alarm. Its combination of dual emergency activation methods, flashing call confirmation, local-only call cancellation, corridor light compatibility, and UL 1069 certification provides a practical emergency signaling solution for maintaining or expanding compatible Tek-CARE NC110, NC150, and NC200 installations.
